I happen to buy used CD from a OCD lady. She was very meticulous. And it was a great buy. They were mainly Alva with microfiber inserts and an extra set of bamboo Inserts. The snaps were in great shape and elastics were strong. She used ABC free & clear but you would want to use detergent without oils & softener.
I wash every 2-3 day (I use a clean litter pail) and I wash them 2x. 1st time I add soap and wash in warm w/ extra rinse. Then rummage through the diapers to make sure all inserts came out and wash in cold. Hot water can destroy the PUL. In the litter pain i keep in the bathtub, all the diapers are removed of poop and residue & I rinse the peed ones too. I find this to have less ammonia smell which can irritate bums. I soak them prior to the wash with oxi clean or borax (I still not sure how this will effect the PUL, but I have no issues so far)
At bed time I combined a microfiber and a bamboo insert. I fold the microfiber about an inch from the top to insure my boy doesn't pee out of it. Baby is changed about the same amount as a disposable and how offen they pee/poop.
-Our water bill is hardly effected.
-beside ridding of the poop that's really only the gross part.
-hardly any diaper rashes and I use a thin layer of whatever, desitin, Vaseline each time so not to clog up the diaper.

With others advice and helps you will come up with a good plan and it will work out well. I was very intimidated and a friend and the lady I purchased from reassured
how easy it is.
Edit: the cost savings are great! As long as you don't go over board. They have some cute stuff out there!
All the best you can PAN me if you like
